I will uninstall the safetynet module and flash the kernel and report back. I'm not at my computer right now but when I get back to it I'll let you know what happensI don't know, possibly yes, as SafteyNet alters that.
These are questions best asked in the Kernel threads, I don't personally disable verity or verification as I don't use custom kernels, I wouldn't be the best source of the info.
As far as PF is concerned, it adds the proper flags to the fastboot command if those options are selected, and we can see that in your logs.
I'm still interested to hear back and learn.
